Can't easilly get to the Horsehead nebula right now, too many permit locked systems around it + it's straight line distance, not distance travelled that counts to unlock Palin.
Oh. Ok.
That´s sad. I did the Horse Head Nebula with a DBX back in 1.3 and was a blast.
Thor´s eye is at 4.2k ly. Is a nice location to go and sightseeing, plus black holes. And then is just some 800ly more and done. Shouldn't be more than 2 days at a very relaxed pace.
